any of the Company’s direct or indirect Subsidiaries will guarantee the Securities of that Series, including the terms of subordination,
if any, of such guarantees.


 


All Securities of any one Series need
not be issued at the same time and may be issued from time to time, consistent with the terms of this Indenture, if so provided by or
pursuant to the Board Resolution, supplemental indenture hereto or Officer’s Certificate referred to above.


 


		Section
                              2.3.	Execution and Authentication.



 


An Officer shall sign the Securities
for the Company by manual, facsimile or electronic signature.


 


If an Officer whose signature
is on a Security no longer holds that office at the time the Security is authenticated, the Security shall nevertheless be valid.


 


A Security shall not be valid
until authenticated by the manual signature of the Trustee or an authenticating agent. The signature shall be conclusive evidence that
the Security has been authenticated under this Indenture.


 


The Trustee shall at any time,
and from time to time, authenticate Securities for original issue in the principal amount provided in the Board Resolution, supplemental
indenture hereto or Officer’s Certificate, upon receipt by the Trustee of a Company Order. Each Security shall be dated the date
of its authentication.


 


The aggregate principal amount
of Securities of any Series outstanding at any time may not exceed any limit upon the maximum principal amount for such Series set
forth in the Board Resolution, supplemental indenture hereto or Officer’s Certificate delivered pursuant to Section 2.2, except
as provided in Section 2.8.


 


Prior to the issuance of Securities
of any Series, the Trustee shall have received and (subject to Section 7.2) shall be fully protected in relying on: (a) the
Board Resolution, supplemental indenture hereto or Officer’s Certificate establishing the form of the Securities of that Series or
of Securities within that Series and the terms of the Securities of that Series or of Securities within that Series, (b) an
Officer’s Certificate complying with Section 10.4, and (c) an Opinion of Counsel complying with Section 10.4.


 


The Trustee shall have the right
to decline to authenticate and deliver any Securities of such Series: (a) if the Trustee, being advised by counsel, determines that
such action may not be taken lawfully; or (b) if the Trustee in good faith by its board of directors or trustees, executive committee
or a trust committee of directors and/or vice-presidents or a committee of Responsible Officers shall determine that such action would
expose the Trustee to personal liability to Holders of any then outstanding Series of Securities.


 






    8


     


    

 


The Trustee may appoint an authenticating
agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may
do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent
has the same rights as an Agent to deal with the Company or an Affiliate of the Company.


 


		Section
                              2.4.	Registrar and Paying Agent.



 


The Company shall maintain,
with respect to each Series of Securities, at the place or places specified with respect to such Series pursuant to Section 2.2,
an office or agency where Securities of such Series may be presented or surrendered for payment (“Paying Agent”),
where Securities of such Series may be surrendered for registration of transfer or exchange (“Registrar”) and
where notices and demands to or upon the Company in respect of the Securities of such Series and this Indenture may be delivered
(“Notice Agent”). The Registrar shall keep a register with respect to each Series of Securities and to their transfer
and exchange. The Company will give prompt written notice to the Trustee of the name and address, and any change in the name or address,
of each Registrar, Paying Agent or Notice Agent. If at any time the Company shall fail to maintain any such required Registrar, Paying
Agent or Notice Agent or shall fail to furnish the Trustee with the name and address thereof, such presentations, surrenders, notices
and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands; provided, however, that any appointment of the Trustee
as the Notice Agent shall exclude the appointment of the Trustee or any office of the Trustee as an agent to receive the service of legal
process on the Company.


 


The Company may also from time
to time designate one or more co-registrars, additional paying agents or additional notice agents and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligations
to maintain a Registrar, Paying Agent and Notice Agent in each place so specified pursuant to Section 2.2 for Securities of any Series for
such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the
name or address of any such co-registrar, additional paying agent or additional notice agent. The term “Registrar”
includes any co-registrar; the term “Paying Agent” includes any additional paying agent; and the term “Notice
Agent” includes any additional notice agent. The Company or any of its Affiliates may serve as Registrar or Paying Agent.


 


The Company hereby appoints
the Trustee the initial Registrar, Paying Agent and Notice Agent for each Series unless another Registrar, Paying Agent or Notice
Agent, as the case may be, is appointed prior to the time Securities of that Series are first issued.


 


		Section
                              2.5.	Paying Agent to Hold Money
in Trust.



 


The Company shall require each
Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust, for the benefit of Securityholders of
any Series of Securities, or the Trustee, all money held by the Paying Agent for the payment of principal of or interest on the Series of
Securities, and will notify the Trustee in writing of any default by the Company in making any such payment. While any such default continues,
the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent
to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or a Subsidiary
of the Company) shall have no further liability for the money. If the Company or a Subsidiary of the Company acts as Paying Agent, it
shall segregate and hold in a separate trust fund for the benefit of Securityholders of any Series of Securities all money held by
it as Paying Agent. Upon any bankruptcy, reorganization or similar proceeding with respect to the Company, the Trustee shall serve as
Paying Agent for the Securities.

		Section
                              2.6.	Securityholder Lists.



 


The Trustee shall preserve in
as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders of each
Series of Securities and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company shall furnish
to the Trustee at least ten days before each interest payment date and at such other times as the Trustee may request in writing a list,
in such form and as of such date as the Trustee may reasonably require, of the names and addresses of Securityholders of each Series of
Securities.


 


		Section
                              2.7.	Transfer and Exchange.



 


Where Securities of a Series are
presented to the Registrar or a co-registrar with a request to register a transfer or to exchange them for an equal principal amount of
Securities of the same Series, the Registrar shall register the transfer or make the exchange if its requirements for such transactions
are met. To permit registrations of transfers and exchanges, the Trustee shall authenticate Securities at the Registrar’s request.
No service charge shall be made for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the
Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith
(other than any such transfer tax or similar governmental charge payable upon exchanges pursuant to Sections 2.11, 3.6 or 9.6).


 


Neither the Company nor the
Registrar shall be required (a) to issue, register the transfer of, or exchange Securities of any Series for the period beginning
at the opening of business 15 days immediately preceding the sending of a notice of redemption of Securities of that Series selected
for redemption and ending at the close of business on the day such notice is sent, or (b) to register the transfer of or exchange
Securities of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such Securities
selected, called or being called for redemption in part.


 


		Section
                              2.8.	Mutilated, Destroyed, Lost
and Stolen Securities.



 


If any mutilated Security is
surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security
of the same Series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.


 


If there shall be delivered
to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such
security or indemnity bond as may be required by each of them to hold itself and any of its agents harmless, then, in the absence of notice
to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon receipt
of a Company Order the Trustee shall authenticate and make available for delivery, in lieu of any such destroyed, lost or stolen Security,
a new Security of the same Series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.


 






    10


     


    

 


In case any such mutilated,
destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing
a new Security, pay such Security.


 


Upon the issuance of any new
Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.


 


Every new Security of any Series issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation
of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled
to all the benefits of this Indenture equally and proportionately with any and all other Securities of that Series duly issued hereunder.


 


The provisions of this Section are
exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities.


 


		Section
                              2.9.	Outstanding Securities.



 


The Securities outstanding at
any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation,
those reductions in the interest on a Global Security effected by the Trustee in accordance with the provisions hereof and those described
in this Section as not outstanding.


 


If a Security is replaced pursuant
to Section 2.8, it ceases to be outstanding until the Trustee receives proof satisfactory to it that the replaced Security is held
by a bona fide purchaser.


 


If the Paying Agent (other than
the Company, a Subsidiary of the Company or an Affiliate of the Company) holds on the Maturity of Securities of a Series money sufficient
to pay such Securities payable on that date, then on and after that date such Securities of the Series cease to be outstanding and
interest on them ceases to accrue.


 


The Company may purchase or
otherwise acquire the Securities, whether by open market purchases, negotiated transactions or otherwise. A Security does not cease to
be outstanding because the Company or an Affiliate of the Company holds the Security (but see Section 2.10 below).


 


In determining whether the Holders
of the requisite principal amount of outstanding Securities have given any request, demand, authorization, direction, notice, consent
or waiver hereunder, the principal amount of a Discount Security that shall be deemed to be outstanding for such purposes shall be the
amount of the principal thereof that would be due and payable as of the date of such determination upon a declaration of acceleration
of the Maturity thereof pursuant to Section 6.2.


 






    11


     


    

 


		Section
                              2.10.	Treasury Securities.



 


In determining whether the Holders
of the required principal amount of Securities of a Series have concurred in any request, demand, authorization, direction, notice,
consent or waiver, Securities of a Series owned by the Company or any Affiliate of the Company shall be disregarded, except that
for the purposes of determining whether the Trustee shall be protected in relying on any such request, demand, authorization, direction,
notice, consent or waiver only Securities of a Series that a Responsible Officer of the Trustee knows are so owned shall be so disregarded.


 


		Section
                              2.11.	Temporary Securities.



 


Until definitive Securities
are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities upon a Company Order. Temporary
Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate
for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee upon receipt of a Company Order shall
authenticate definitive Securities of the same Series and date of maturity in exchange for temporary Securities. Until so exchanged,
temporary securities shall have the same rights under this Indenture as the definitive Securities.


 


		Section
                              2.12.	Cancellation.



 


The Company at any time may
deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered
to them for registration of transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for transfer, exchange,
payment, replacement or cancellation and shall destroy such canceled Securities (subject to the record retention requirement of the Exchange
Act and the Trustee) and deliver a certificate of such cancellation to the Company upon written request of the Company. The Company may
not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation.


 


		Section
                              2.13.	Defaulted Interest.



 


If the Company defaults in a
payment of interest on a Series of Securities, it shall pay the defaulted interest, plus, to the extent permitted by law, any interest
payable on the defaulted interest, to the persons who are Securityholders of the Series on a subsequent special record date. The
Company shall fix the record date and payment date. At least ten days before the special record date, the Company shall send to the Trustee
and to each Securityholder of the Series a notice that states the special record date, the payment date and the amount of interest
to be paid. The Company may pay defaulted interest in any other lawful manner.

		Section
                              2.14.	Global Securities.



 


2.14.1.          Terms
of Securities. A Board Resolution, a supplemental indenture hereto or an Officer’s Certificate shall establish whether the Securities
of a Series shall be issued in whole or in part in the form of one or more Global Securities and the Depositary for such Global Security
or Securities.


 


2.14.2.          Transfer
and Exchange. Notwithstanding any provisions to the contrary contained in Section 2.7 of the Indenture and in addition thereto,
any Global Security shall be exchangeable pursuant to Section 2.7 of the Indenture for Securities registered in the names of Holders
other than the Depositary for such Security or its nominee only if (i) such Depositary notifies the Company that it is unwilling
or unable to continue as Depositary for such Global Security or if at any time such Depositary ceases to be a clearing agency registered
under the Exchange Act, and, in either case, the Company fails to appoint a successor Depositary registered as a clearing agency under
the Exchange Act within 90 days of such event or (ii) the Company executes and delivers to the Trustee an Officer’s Certificate
to the effect that such Global Security shall be so exchangeable. Any Global Security that is exchangeable pursuant to the preceding sentence
shall be exchangeable for Securities registered in such names as the Depositary shall direct in writing in an aggregate principal amount
equal to the principal amount of the Global Security with like tenor and terms.


 


Except as provided in this Section 2.14.2,
a Global Security may not be transferred except as a whole by the Depositary with respect to such Global Security to a nominee of such
Depositary, by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by the Depositary or any such
nominee to a successor Depositary or a nominee of such a successor Depositary.


 


2.14.3.          Legends.
Any Global Security issued hereunder shall bear a legend in substantially the following form:


 


“THIS SECURITY IS A GLOBAL
SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF THE DEPOSITARY OR A NOMINEE OF THE
DEPOSITARY. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY
IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE
OF THE DEPOSITARY, BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH
NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH A SUCCESSOR DEPOSITARY.”


 


In addition, so long as the
Depository Trust Company (“DTC”) is the Depositary, each Global Note registered in the name of DTC or its nominee shall bear
a legend in substantially the following form:


 


“UNLESS THIS GLOBAL NOTE
IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), TO THE COMPANY
OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY GLOBAL NOTE ISSUED IS REGISTERED IN THE NAME OF CEDE &
CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO
SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE
BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.”


 






    13


     


    

 


2.14.4.          Acts
of Holders. The Depositary, as a Holder, may appoint agents and otherwise authorize participants to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under the Indenture.


 


2.14.5.          Payments.
Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by Section 2.2, payment of the
principal of and interest, if any, on any Global Security shall be made to the Holder thereof.


 


2.14.6.          Consents,
Declaration and Directions. The Company, the Trustee and any Agent shall treat a person as the Holder of such principal amount of
outstanding Securities of such Series represented by a Global Security as shall be specified in a written statement of the Depositary
or by the applicable procedures of the Depositary with respect to such Global Security, for purposes of obtaining any consents, declarations,
waivers or directions required to be given by the Holders pursuant to this Indenture.


 


		Section
                              2.15.	CUSIP Numbers.



 


The Company in issuing the Securities
may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices
of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness
of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only
on the other elements of identification printed on the Securities, and any such redemption shall not be affected by any defect in or omission
of such numbers.


 


ARTICLE III.

REDEMPTION


 


		Section
                              3.1.	Notice to Trustee.

to any Series of Securities, reserve the right to redeem and pay the Series of Securities or may covenant to redeem and pay
the Series of Securities or any part thereof prior to the Stated Maturity thereof at such time and on such terms as provided for
in such Securities. If a Series of Securities is redeemable and the Company wants or is obligated to redeem prior to the Stated Maturity
thereof all or part of the Series of Securities pursuant to the terms of such Securities, it shall notify the Trustee in writing
of the redemption date and the principal amount of the Series of Securities to be redeemed. The Company shall give the notice at
least 15 days before the redemption date, unless a shorter period is satisfactory to the Trustee.

		Section
                              3.2.	Selection of Securities to
be Redeemed.



 


Unless otherwise indicated for
a particular Series by a Board Resolution, a supplemental indenture hereto or an Officer’s Certificate, if less than all the
Securities of a Series are to be redeemed, the Securities of the Series to be redeemed will be selected as follows: (a) if
the Securities are in the form of Global Securities, in accordance with the procedures of the Depositary, (b) if the Securities are
listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange, if any,
on which the Securities are listed, or (c) if not otherwise provided for under clause (a) or (b) in the manner that the
Trustee deems fair and appropriate, including by lot or other method, unless otherwise required by law or applicable stock exchange requirements,
subject, in the case of Global Securities, to the applicable rules and procedures of the Depositary. The Securities to be redeemed
shall be selected from Securities of the Series outstanding not previously called for redemption. Portions of the principal of Securities
of the Series that have denominations larger than $1,000 may be selected for redemption. Securities of the Series and portions
of them it selected for redemption shall be in amounts of $1,000 or whole multiples of $1,000 or, with respect to Securities of any Series issuable
in other denominations pursuant to Section 2.2.10, the minimum principal denomination for each Series and the authorized integral
multiples thereof. Provisions of this Indenture that apply to Securities of a Series called for redemption also apply to portions
of Securities of that Series called for redemption.


 


		Section
                              3.3.	Notice of Redemption.



 


Unless otherwise indicated for
a particular Series by Board Resolution, a supplemental indenture hereto or an Officer’s Certificate, at least 15 days but
not more than 60 days before a redemption date, the Company shall send or cause to be sent by first-class mail or electronically, in accordance
with the procedures of the Depositary, a notice of redemption to each Holder whose Securities are to be redeemed.


 


The notice shall identify the
Securities of the Series to be redeemed and shall state:


 


(a)             the
redemption date;


 


(b)             the
redemption price;


 


(c)             the
name and address of the Paying Agent;


 


(d)             if
any Securities are being redeemed in part, the portion of the principal amount of such Securities to be redeemed and that, after the redemption
date and upon surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion of the original
Security shall be issued in the name of the Holder thereof upon cancellation of the original Security;


 


(e)             that
Securities of the Series called for redemption must be surrendered to the Paying Agent to collect the redemption price;


 






    15


     


    

 


(f)             that
interest on Securities of the Series called for redemption ceases to accrue on and after the redemption date unless the Company defaults
in the deposit of the redemption price;


 


(g)            the
CUSIP number, if any; and


 


(h)            any
other information as may be required by the terms of the particular Series or the Securities of a Series being redeemed.


 


At the Company’s request,
the Trustee shall give the notice of redemption in the Company’s name and at its expense, provided, however, that the Company has
delivered to the Trustee, at least 10 days (unless a shorter time shall be acceptable to the Trustee) prior to the notice date, an Officer’s
Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice.


 


Section 3.4.            Effect
of Notice of Redemption.


 


Once notice of redemption is
sent as provided in Section 3.3, Securities of a Series called for redemption become due and payable on the redemption date
and at the redemption price. Except as otherwise provided in the supplemental indenture, Board Resolution or Officer’s Certificate
for a Series, a notice of redemption may not be conditional. Upon surrender to the Paying Agent, such Securities shall be paid at the
redemption price plus accrued interest to the redemption date.


 


Section 3.5.            Deposit
of Redemption Price.


 


On or before 11:00 a.m., New
York City time, on the redemption date, the Company shall deposit with the Paying Agent money sufficient to pay the redemption price of
and accrued interest, if any, on all Securities to be redeemed on that date.


 


Section 3.6.            Securities
Redeemed in Part.


 


Upon surrender of a Security
that is redeemed in part, the Trustee shall authenticate for the Holder a new Security of the same Series and the same maturity equal
in principal amount to the unredeemed portion of the Security surrendered.

COVENANTS


 


Section 4.1.            Payment

The Company covenants and agrees
for the benefit of the Holders of each Series of Securities that it will duly and punctually pay the principal of and interest, if
any, on the Securities of that Series in accordance with the terms of such Securities and this Indenture. On or before 11:00 a.m.,

Section 4.2.            SEC
Reports.


 


To the extent any Securities
of a Series are outstanding, the Company shall deliver to the Trustee within 15 days after it files them with the SEC copies of the
annual reports and of the information, documents, and other reports (or copies of such portions of any of the foregoing as the SEC may
by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of
the Exchange Act. The Company also shall comply with the other provisions of TIA § 314(a). Reports, information and documents filed
with the SEC via the EDGAR system will be deemed to be delivered to the Trustee as of the time of such filing via EDGAR for purposes of
this Section 4.2.


 


Delivery of reports, information
and documents to the Trustee under this Section 4.2 is for informational purposes only and the Trustee’s receipt of the foregoing
shall not constitute constructive or actual notice of any information contained therein or determinable from information contained therein,
including the Company’s compliance with any of the covenants hereunder (as to which the Trustee is entitled to rely exclusively
on Officer’s Certificates). All such reports, information or documents referred to in this Section 4.2 that the Company files
with the SEC via the SEC’s EDGAR system shall be deemed to be filed with the Trustee and transmitted to Holders at the time such
reports, information or documents are filed via the EDGAR system (or any successor system).


 


Section 4.3.            Compliance
Certificate.


 


To the extent any Securities
of a Series are outstanding, the Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company,
an Officer’s Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal
year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept, observed, performed
and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the
best of his/her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture
and is not in default in the performance or observance of any of the terms, provisions and conditions hereof (or, if a Default or Event
of Default shall have occurred, describing all such Defaults or Events of Default of which the Officer may have knowledge).


 


Section 4.4.            Stay,
Extension and Usury Laws.


 


The Company covenants (to the
extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit
or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture or the Securities; and the Company (to the extent it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law and covenants that it will not, by resort to any such law, hinder, delay or impede the execution
of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been
enacted.

Section 5.1.            When
Company May Merge, Etc.


 


The Company shall not consolidate
with or merge with or into, or convey, transfer or lease all or substantially all of its properties and assets to, any person (a “successor
person”) unless:


 


(a)            the
Company is the surviving entity or the successor person (if other than the Company) is a corporation, partnership, trust or other entity
organized and validly existing under the laws of any U.S. domestic jurisdiction and expressly assumes the Company’s obligations
on the Securities and under this Indenture; and


 


(b)            immediately

The Company shall deliver to
the Trustee prior to the consummation of the proposed transaction an Officer’s Certificate to the foregoing effect and an Opinion
of Counsel stating that the proposed transaction and any supplemental indenture comply with this Indenture.


 


Notwithstanding the above, any
Subsidiary of the Company may consolidate with, merge into or transfer all or part of its properties to the Company. Neither an Officer’s
Certificate nor an Opinion of Counsel shall be required to be delivered in connection therewith.


 


Section 5.2.            Successor
Corporation Substituted.


 


Upon any consolidation or merger,
or any sale, lease, conveyance or other disposition of all or substantially all of the assets of the Company in accordance with Section 5.1,
the successor corporation formed by such consolidation or into or with which the Company is merged or to which such sale, lease, conveyance
or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this
Indenture with the same effect as if such successor person has been named as the Company herein; provided, however, that
the predecessor Company in the case of a sale, conveyance or other disposition (other than a lease) shall be released from all obligations
and covenants under this Indenture and the Securities.

Section 6.1.            Events
of Default.


 


“Event of Default,”
wherever used herein with respect to Securities of any Series, means any one of the following events, unless in the establishing Board
Resolution, supplemental indenture or Officer’s Certificate, it is provided that such Series shall not have the benefit of
said Event of Default:


 


(a)            default
in the payment of any interest on any Security of that Series when it becomes due and payable, and continuance of such default for
a period of 30 days (unless the entire amount of such payment is deposited by the Company with the Trustee or with a Paying Agent prior

in the payment of principal of any Security of that Series at its Maturity; or

in the performance or breach of any covenant or warranty of the Company in this Indenture (other than defaults pursuant to paragraph (a) or
(b) above or pursuant to a covenant or warranty that has been included in this Indenture solely for the benefit of a Series of
Securities other than that Series), which default continues uncured for a period of 60 days after there has been given, by registered
or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount
of the outstanding Securities of that Series a written notice specifying such default or breach and requiring it to be remedied and
stating that such notice is a “Notice of Default” hereunder; or


 


(d)            the
Company pursuant to or within the meaning of any Bankruptcy Law:


 


(i)            commences
a voluntary case,


 


(ii)           consents
to the entry of an order for relief against it in an involuntary case,


 


(iii)          consents
to the appointment of a Custodian of it or for all or substantially all of its property,


 


(iv)          makes
a general assignment for the benefit of its creditors, or


 


(v)           generally
is unable to pay its debts as the same become due; or


 


(e)            a
court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:


 


(i)            is
for relief against the Company in an involuntary case,


 


(ii)           appoints
a Custodian of the Company or for all or substantially all of its property, or


 


(iii)          orders

and the order or decree remains unstayed
and in effect for 60 days; or


 


(f)             any
other Event of Default provided with respect to Securities of that Series, which is specified in a Board Resolution, a supplemental indenture
hereto or an Officer’s Certificate, in accordance with Section 2.2.18.


 






    19


     


    

 


The term “Bankruptcy
Law” means title 11, U.S. Code or any similar Federal or State law for the relief of debtors. The term “Custodian”
means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law.


 


The Company will provide the
Trustee written notice of any Default or Event of Default within 30 days of becoming aware of the occurrence of such Default or Event
of Default, which notice will describe in reasonable detail the status of such Default or Event of Default and what action the Company
is taking or proposes to take in respect thereof.


 


Section 6.2.            Acceleration
of Maturity; Rescission and Annulment.


 


If an Event of Default with
respect to Securities of any Series at the time outstanding occurs and is continuing (other than an Event of Default referred to
in Section 6.1(d) or (e)) then in every such case the Trustee or the Holders of not less than 25% in principal amount of the
outstanding Securities of that Series may declare the principal amount (or, if any Securities of that Series are Discount Securities,
such portion of the principal amount as may be specified in the terms of such Securities) of and accrued and unpaid interest, if any,
on all of the Securities of that Series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee
if given by Holders), and upon any such declaration such principal amount (or specified amount) and accrued and unpaid interest, if any,
shall become immediately due and payable. If an Event of Default specified in Section 6.1(d) or (e) shall occur, the principal
amount (or specified amount) of and accrued and unpaid interest, if any, on all outstanding Securities shall ipso facto become
and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.


 


At any time after such a declaration
of acceleration with respect to any Series has been made and before a judgment or decree for payment of the money due has been obtained
by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the outstanding Securities
of that Series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if all Events
of Default with respect to Securities of that Series, other than the non-payment of the principal and interest, if any, of Securities
of that Series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 6.13.


 


No such rescission shall affect
any subsequent Default or impair any right consequent thereon.


 


Section 6.3.            Collection
of Indebtedness and Suits for Enforcement by Trustee.


 


The Company covenants that if:


 


(a)            default
is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period
of 30 days, or


 


(b)            default
is made in the payment of principal of any Security at the Maturity thereof, or


 






    20


     


    

 


(c)            default
is made in the deposit of any sinking fund payment, if any, when and as due by the terms of a Security,


 


then,
the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due
and payable on such Securities for principal and interest and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal and any overdue interest at the rate or rates prescribed therefor in such Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the compensation, reasonable
expenses, disbursements and advances of the Trustee, its agents and counsel.


 


If the Company fails to pay
such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding
for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against
the Company or any other obligor upon such Securities and collect the moneys adjudged or deemed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon such Securities, wherever situated.


 


If an Event of Default with
respect to any Securities of any Series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such Series by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.


 


Section 6.4.            Trustee
May File Proofs of Claim.


 


In case of the pendency of any
receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative
to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the
Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or
interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,


 


(a)            to
file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Securities and to file such other
papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the compensation,
reasonable expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding,
and


 






    21


     


    

 








(b)            to
collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due it for the compensation, reasonable expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.7.


 


Nothing herein contained shall
be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.


 


Section 6.5.            Trustee
May Enforce Claims Without Possession of Securities.


 


All rights of action and claims
under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or
the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the compensation, reasonable
expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities
in respect of which such judgment has been recovered.


 


Section 6.6.            Application
of Money Collected.


 


Any money or property collected
by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in
case of the distribution of such money or property on account of principal or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if fully paid:


 


First:                  To
the payment of all amounts due the Trustee under Section 7.7; and


 


Second:            To
the payment of the amounts then due and unpaid for principal of and interest on the Securities in respect of which or for the benefit
of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable
on such Securities for principal and interest, respectively; and


 


Third:                To
the Company.


 


Section 6.7.            Limitation
on Suits.


 


No Holder of any Security of
any Series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment
of a receiver or trustee, or for any other remedy hereunder, unless


 


(a)            such
Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that Series;


 






    22


     


    

 


(b)            the
Holders of not less than 25% in principal amount of the outstanding Securities of that Series shall have made written request to
the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;


 


(c)            such
Holder or Holders have offered to the Trustee indemnity or security satisfactory to the Trustee against the costs, expenses and liabilities
which might be incurred by the Trustee in compliance with such request;


 


(d)            the
Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and


 


(e)            no
direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority
in principal amount of the outstanding Securities of that Series;


 


it being understood, intended and expressly covenanted
by the Holder of every Security with every other Holder and the Trustee that no one or more of such Holders shall have any right in any
manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other
of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under
this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders of the applicable Series.


 


Section 6.8.            Unconditional
Right of Holders to Receive Principal and Interest.


 


Notwithstanding any other provision
in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal
of and interest, if any, on such Security on the Maturity of such Security, including the Stated Maturity expressed in such Security (or,
in the case of redemption, on the redemption date) and to institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.


 


Section 6.9.            Restoration
of Rights and Remedies.


 


If the Trustee or any Holder
has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned
for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination
in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder
and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.


 


Section 6.10.          Rights
and Remedies Cumulative.


 


Except as otherwise provided
with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in Section 2.8, no right or remedy
herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder
or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise,
shall not, to the extent permitted by law, prevent the concurrent assertion or employment of any other appropriate right or remedy.


 






    23


     


    

 


Section 6.11.          Delay
or Omission Not Waiver.


 


No delay or omission of the
Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right
or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or
by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or
by the Holders, as the case may be.


 


Section 6.12.          Control
by Holders.


 


The Holders of a majority in
principal amount of the outstanding Securities of any Series shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the
Securities of such Series, provided that


 


(a)            such
direction shall not be in conflict with any rule of law or with this Indenture,


 


(b)            the
Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction,


 


(c)            subject
to the provisions of Section 7.1, the Trustee shall have the right to decline to follow any such direction if the Trustee in good
faith shall, by a Responsible Officer of the Trustee, determine that the proceeding so directed would involve the Trustee in personal
liability, and


 


(d)            prior
to taking any action as directed under this Section 6.12, the Trustee shall be entitled to indemnity satisfactory to it against the
costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.


 


Section 6.13.          Waiver
of Past Defaults.


 


The Holders of not less than
a majority in principal amount of the outstanding Securities of any Series may on behalf of the Holders of all the Securities of
such Series, by written notice to the Trustee and the Company, waive any past Default hereunder with respect to such Series and its
consequences, except a Default in the payment of the principal of or interest on any Security of such Series (provided, however,
that the Holders of a majority in principal amount of the outstanding Securities of any Series may rescind an acceleration and its
consequences, including any related payment default that resulted from such acceleration). Upon any such waiver, such Default shall cease
to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other Default or impair any right consequent thereon.


 






    24


     


    

 


Section 6.14.          Undertaking
for Costs.


 


All parties to this Indenture
agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion
require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action
taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party
litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions
of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted
by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the outstanding Securities of any Series,
or to any suit instituted by any Holder for the enforcement of the payment of the principal of or interest on any Security on or after
the Maturity of such Security, including the Stated Maturity expressed in such Security (or, in the case of redemption, on the redemption
date).


 


ARTICLE VII.

TRUSTEE


 


Section 7.1.            Duties
of Trustee.


 


(a)            If
an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and
use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct
of such person’s own affairs.


 


(b)            Except
during the continuance of an Event of Default:


 


(i)            The
Trustee need perform only those duties that are specifically set forth in this Indenture and no others.


 


(ii)           In
the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon Officer’s Certificates or Opinions of Counsel furnished to the Trustee and conforming to the requirements
of this Indenture; however, in the case of any such Officer’s Certificates or Opinions of Counsel which by any provisions
hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such Officer’s Certificates and Opinions
of Counsel to determine whether or not they conform to the form requirements of this Indenture.


 






    25


     


    

 



 


(c)            The
Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct,
except that:


 


(i)            This
paragraph does not limit the effect of paragraph (b) of this Section.


 


(ii)           The
Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee
was negligent in ascertaining the pertinent facts.


 


(iii)          The
Trustee shall not be liable with respect to any action taken, suffered or omitted to be taken by it with respect to Securities of any
Series in good faith in accordance with the direction of the Holders of a majority in principal amount of the outstanding Securities
of such Series relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such Series in accordance with
Section 6.12.


 


(d)            Every
provision of this Indenture that in any way relates to the Trustee is subject to paragraph (a), (b) and (c) of this Section.


 


(e)            The
Trustee may refuse to perform any duty or exercise any right or power unless it receives indemnity satisfactory to it against the costs,
expenses and liabilities which might be incurred by it in performing such duty or exercising such right or power.


 


(f)            The
Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money
held in trust by the Trustee need not be segregated from other funds except to the extent required by law.


 


(g)            No
provision of this Indenture shall require the Trustee to risk its own funds or otherwise incur any financial liability in the performance
of any of its duties, or in the exercise of any of its rights or powers, if adequate indemnity against such risk is not assured to the
Trustee in its satisfaction.


 


(h)            The
Paying Agent, the Registrar and any authenticating agent shall be entitled to the protections and immunities as are set forth in paragraphs
(e), (f) and (g) of this Section and in Section 7.2, each with respect to the Trustee.


 


Section 7.2.            Rights
of Trustee.


 


(a)            The
Trustee may rely on and shall be protected in acting or refraining from acting upon any document (whether in its original or facsimile
form) believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact
or matter stated in the document.


 


(b)            Before
the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both. The Trustee
shall not be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion
of Counsel.


 


(c)            The
Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. No
Depositary shall be deemed an agent of the Trustee and the Trustee shall not be responsible for any act or omission by any Depositary.


 






    26 


     


    

 


(d)            The
Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights
or powers, provided that the Trustee’s conduct does not constitute willful misconduct or negligence.


 


(e)            The
Trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted by it hereunder without willful misconduct or negligence, and in reliance
thereon.


 


(f)            The
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction
of any of the Holders of Securities unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against
the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.


 


(g)            The
Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document,
but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit.


 


(h)            The
Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge
thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office
of the Trustee, and such notice references the Securities generally or the Securities of a particular Series and this Indenture.


 


(i)             In
no event shall the Trustee be liable to any person for special, punitive, indirect, consequential or incidental loss or damage of any
kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage.


 


(j)             The
permissive right of the Trustee to take the actions permitted by this Indenture shall not be construed as an obligation or duty to do
so.


 


Section 7.3.            Individual
Rights of Trustee.


 


The Trustee in its individual
or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or an Affiliate of the Company
with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. The Trustee is also subject to
Sections 7.10 and 7.11.


 


Section 7.4.            Trustee’s
Disclaimer.


 


The Trustee makes no representation
as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds

    27 


     


    

 


Section 7.5.            Notice
of Defaults.


 


If a Default or Event of Default
occurs and is continuing with respect to the Securities of any Series and if it is known to a Responsible Officer of the Trustee,
the Trustee shall send to each Securityholder of the Securities of that Series notice of a Default or Event of Default within 90
days after it occurs or, if later, after a Responsible Officer of the Trustee has knowledge of such Default or Event of Default. Except
in the case of a Default or Event of Default in payment of principal of or interest on any Security of any Series, the Trustee may withhold
the notice if and so long as its corporate trust committee or a committee of its Responsible Officers in good faith determines that withholding
the notice is in the interests of Securityholders of that Series.


 


Section 7.6.            Reports
by Trustee to Holders.


 


Within 60 days after each [[
] commencing [ ], [ ]], the Trustee shall transmit by mail to all Securityholders, as their names and addresses appear on the register
kept by the Registrar, a brief report dated as of such anniversary date, in accordance with, and to the extent required under, TIA §
313.


 


A copy of each report at the
time of its mailing to Securityholders of any Series shall be filed with the SEC and each national securities exchange on which the
Securities of that Series are listed. The Company shall promptly notify the Trustee in writing when Securities of any Series are
listed on any national securities exchange.


 


Section 7.7.            Compensation
and Indemnity.


 


The Company shall pay to the
Trustee from time to time compensation for its services as the Company and the Trustee shall from time to time agree upon in writing.
The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse
the Trustee upon request for all reasonable out of pocket expenses incurred by it. Such expenses shall include the reasonable compensation
and expenses of the Trustee’s agents and counsel.


 


The Company shall indemnify
each of the Trustee and any predecessor Trustee (including for the cost of defending itself) against any cost, expense or liability, including
taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred by it except as set forth in the
next paragraph in the performance of its duties under this Indenture as Trustee or Agent. The Trustee shall notify the Company promptly
of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations
hereunder, unless and to the extent that the Company is materially prejudiced thereby. The Company shall defend the claim and the Trustee
shall cooperate in the defense. The Trustee may have one separate counsel and the Company shall pay the reasonable fees and expenses of
such counsel. The Company need not pay for any settlement made without its consent, which consent will not be unreasonably withheld. This
indemnification shall apply to officers, directors, employees, shareholders and agents of the Trustee.


 


The Company need not reimburse
any expense or indemnify against any loss or liability incurred by the Trustee or by any officer, director, employee, shareholder or agent
of the Trustee through willful misconduct or negligence.


 






    28 


     


    

 


To secure the Company’s
payment obligations in this Section, the Trustee shall have a lien prior to the Securities of any Series on all money or property
held or collected by the Trustee, except that held in trust to pay principal of and interest on particular Securities of that Series.

or renders services after an Event of Default specified in Section 6.1(d) or (e) occurs, the expenses and the compensation
for the services are intended to constitute expenses of administration under any Bankruptcy Law.

Section 7.8.            Replacement
of Trustee.

as provided in this Section.


 


The Trustee may resign with
respect to the Securities of one or more Series by so notifying the Company at least 30 days prior to the date of the proposed resignation.
The Holders of a majority in principal amount of the Securities of any Series may remove the Trustee with respect to that Series by
so notifying the Trustee and the Company. The Company may remove the Trustee with respect to Securities of one or more Series if:


 


(a)            the
Trustee fails to comply with Section 7.10;


 


(b)            the
Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

Custodian or public officer takes charge of the Trustee or its property; or


 


(d)            the
Trustee becomes incapable of acting.

removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within
one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Securities may
appoint a successor Trustee to replace the successor Trustee appointed by the Company.


 


If a successor Trustee with
respect to the Securities of any one or more Series does not take office within 60 days after the retiring Trustee resigns or is
removed, the retiring Trustee, the Company or the Holders of at least a majority in principal amount of the Securities of the applicable
Series may petition any court of competent jurisdiction for the appointment of a successor Trustee.


 






    29 


     


    

 


A successor Trustee shall deliver
a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that, the retiring Trustee shall
transfer all property held by it as Trustee to the successor Trustee subject to the lien provided for in Section 7.7, the resignation
or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the
Trustee with respect to each Series of Securities for which it is acting as Trustee under this Indenture. A successor Trustee shall
mail a notice of its succession to each Securityholder of each such Series. Notwithstanding replacement of the Trustee pursuant to this
Section 7.8, the Company’s obligations under Section 7.7 hereof shall continue for the benefit of the retiring Trustee
with respect to expenses and liabilities incurred by it for actions taken or omitted to be taken in accordance with its rights, powers
and duties under this Indenture prior to such replacement.


 


Section 7.9.            Successor
Trustee by Merger, Etc.


 


If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor
corporation without any further act shall be the successor Trustee, subject to Section 7.10.

have a Trustee who satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee shall always have a combined capital

 § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject
to TIA § 311(a) to the extent indicated.

bank expressed in a written certification thereof delivered to the Trustee, to pay and discharge each installment of principal of and

of principal or interest and such sinking fund payments are due;


 






    32

such Opinion of Counsel shall confirm that, the Holders of the Securities of such Series will not recognize income, gain or loss
for Federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to Federal income tax on the
same amount and in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not
occurred;


 


(h)            the
Company shall have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by the Company with the
intent of defeating, hindering, delaying or defrauding any other creditors of the Company; and

Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to the defeasance contemplated by this Section have been complied with.


 






    33 


     


    

 


Section 8.4.            Covenant
Defeasance.


 


Unless this Section 8.4
is otherwise specified pursuant to Section 2.2 to be inapplicable to Securities of any Series, the Company may omit to comply with
respect to the Securities of any Series with any term, provision or condition set forth under Sections 4.2, 4.3, 4.4 and 5.1 and,
unless otherwise specified therein, any additional covenants specified in a supplemental indenture for such Series of Securities
or a Board Resolution or an Officer’s Certificate delivered pursuant to Section 2.2 (and the failure to comply with any such
covenants shall not constitute a Default or Event of Default with respect to such Series under Section 6.1) and the occurrence
of any event specified in a supplemental indenture for such Series of Securities or a Board Resolution or an Officer’s Certificate
delivered pursuant to Section 2.2 and designated as an Event of Default shall not constitute a Default or Event of Default hereunder,
with respect to the Securities of such Series, but, except as specified above, the remainder of this Indenture and such Securities will
be unaffected thereby; provided that the following conditions shall have been satisfied:


 


(a)            with
reference to this Section 8.4, the Company has irrevocably deposited or caused to be irrevocably deposited (except as provided in
Section 8.2(c)) with the Trustee as trust funds in trust for the purpose of making the following payments specifically pledged as
security for, and dedicated solely to, the benefit of the Holders of such Securities (i) in the case of Securities of such Series denominated
in Dollars, cash in Dollars and/or U.S. Government Obligations, or (ii) in the case of Securities of such Series denominated
in a Foreign Currency (other than a composite currency), money and/or Foreign Government Obligations, which through the payment of interest
and principal in respect thereof in accordance with their terms, will provide (and without reinvestment and assuming no tax liability
will be imposed on such Trustee), not later than one day before the due date of any payment of money, an amount in cash, sufficient, in
the opinion of a nationally recognized firm of independent certified public accountants or investment bank expressed in a written certification
thereof delivered to the Trustee, to pay and discharge each installment of principal (including mandatory sinking fund or analogous payments)
of and interest on all the Securities of such Series on the dates such installments of principal or interest are due;


 


(b)            such
deposit will not result in a breach or violation of, or constitute a default under, this Indenture or any other agreement or instrument
to which the Company is a party or by which it is bound;


 


(c)            no
Default or Event of Default with respect to the Securities of such Series shall have occurred and be continuing on the date of such
deposit;


 


(d)            the
Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel to the effect that the Holders of
the Securities of such Series will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit
and covenant defeasance and will be subject to Federal income tax on the same amount and in the same manner and at the same times as would
have been the case if such deposit and covenant defeasance had not occurred;


 


(e)            The
Company shall have delivered to the Trustee an Officer’s Certificate stating the deposit was not made by the Company with the intent
of defeating, hindering, delaying or defrauding any other creditors of the Company; and

precedent herein provided for relating to the covenant defeasance contemplated by this Section have been complied with.

to Company.


 


Subject to applicable abandoned
property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal
and interest that remains unclaimed for two years. After that, Securityholders entitled to the money must look to the Company for payment
as general creditors unless an applicable abandoned property law designates another person.


 






    34 


     


    

 


Section 8.6.            Reinstatement.


 


If the Trustee or the Paying
Agent is unable to apply any money deposited with respect to Securities of any Series in accordance with Section 8.1 by reason
of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, the obligations of the Company under this Indenture with respect to the Securities of such Series and
under the Securities of such Series shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.1
until such time as the Trustee or the Paying Agent is permitted to apply all such money in accordance with Section 8.1; provided,
however, that if the Company has made any payment of principal of or interest on any Securities because of the reinstatement of
its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money
or U.S. Government Obligations held by the Trustee or Paying Agent after payment in full to the Holders.


 


ARTICLE IX.

AMENDMENTS AND WAIVERS

cure any ambiguity, defect or inconsistency;


 


(b)            to

(k)            to

    35 


     


    

 


Section 9.2.            With
Consent of Holders.


 


The Company and the Trustee
may enter into a supplemental indenture with the written consent of the Holders of at least a majority in principal amount of the outstanding
Securities of each Series affected by such supplemental indenture (including consents obtained in connection with a tender offer
or exchange offer for the Securities of such Series), for the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the Securityholders
of each such Series. Except as provided in Section 6.13, the Holders of at least a majority in principal amount of the outstanding
Securities of any Series by notice to the Trustee (including consents obtained in connection with a tender offer or exchange offer
for the Securities of such Series) may waive compliance by the Company with any provision of this Indenture or the Securities with respect
to such Series.


 


It shall not be necessary for
the consent of the Holders of Securities under this Section 9.2 to approve the particular form of any proposed supplemental indenture
or waiver, but it shall be sufficient if such consent approves the substance thereof. After a supplemental indenture or waiver under this
section becomes effective, the Company shall send to the Holders of Securities affected thereby, a notice briefly describing the supplemental
indenture or waiver. Any failure by the Company to send such notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture or waiver.


 


Section 9.3.            Limitations.


 


Without the consent of each
Securityholder affected, an amendment or waiver may not:


 


(a)            reduce
the principal amount of Securities whose Holders must consent to an amendment, supplement or waiver;


 


(b)            reduce
the rate of or extend the time for payment of interest (including default interest) on any Security;


 


(c)            reduce
the principal or change the Stated Maturity of any Security or reduce the amount of, or postpone the date fixed for, the payment of any
sinking fund or analogous obligation;


 


(d)            reduce
the principal amount of Discount Securities payable upon acceleration of the maturity thereof;


 


(e)            waive
a Default or Event of Default in the payment of the principal of or interest, if any, on any Security (except a rescission of acceleration
of the Securities of any Series by the Holders of at least a majority in principal amount of the outstanding Securities of such Series and
a waiver of the payment default that resulted from such acceleration);


 






    36 


     


    

 


(f)            make
the principal of or interest, if any, on any Security payable in any currency other than that stated in the Security;


 


(g)            make
any change in Sections 6.8, 6.13 or 9.3 (this sentence); or


 


(h)            waive
a redemption payment with respect to any Security, provided that such redemption is made at the Company’s option.


 


Section 9.4.            Compliance
with Trust Indenture Act.


 


Every amendment to this Indenture
or the Securities of one or more Series shall be set forth in a supplemental indenture hereto that complies with the TIA as then
in effect.


 


Section 9.5.            Revocation
and Effect of Consents.


 


Until an amendment is set forth
in a supplemental indenture or a waiver becomes effective, a consent to it by a Holder of a Security is a continuing consent by the Holder
and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security,
even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to
his Security or portion of a Security if the Trustee receives the notice of revocation before the date of the supplemental indenture or
the date the waiver becomes effective.


 


Any amendment or waiver once
effective shall bind every Securityholder of each Series affected by such amendment or waiver unless it is of the type described
in any of clauses (a) through (h) of Section 9.3. In that case, the amendment or waiver shall bind each Holder of a Security
who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting
Holder’s Security.


 


The Company may, but shall not
be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action
described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the second
immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those
persons, shall be entitled to give such consent or to revoke any consent previously given or take any such action, whether or not such
Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record
date.


 


Section 9.6.            Notation
on or Exchange of Securities.


 


The Company or the Trustee may
place an appropriate notation about an amendment or waiver on any Security of any Series thereafter authenticated. The Company in
exchange for Securities of that Series may issue and the Trustee shall authenticate upon receipt of a Company Order in accordance
with Section 2.3 new Securities of that Series that reflect the amendment or waiver.


 






    37 


     


    

 


Section 9.7.            Trustee
Protected.


 


In executing, or accepting the
additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created
by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 7.1) shall be fully protected in relying upon,
an Officer’s Certificate or an Opinion of Counsel or both complying with Section 10.4. The Trustee shall sign all supplemental
indentures upon delivery of such an Officer’s Certificate or Opinion of Counsel or both, except that the Trustee need not sign any
supplemental indenture that adversely affects its rights, duties, liabilities or immunities under this Indenture.

Section 10.15.        Securities
in a Foreign Currency.


 


Unless otherwise specified in
a Board Resolution, a supplemental indenture hereto or an Officer’s Certificate delivered pursuant to Section 2.2 of this Indenture
with respect to a particular Series of Securities, whenever for purposes of this Indenture any action may be taken by the Holders
of a specified percentage in aggregate principal amount of Securities of all Series or all Series affected by a particular action
at the time outstanding and, at such time, there are outstanding Securities of any Series which are denominated in more than one
currency, then the principal amount of Securities of such Series which shall be deemed to be outstanding for the purpose of taking
such action shall be determined by converting any such other currency into a currency that is designated upon issuance of any particular
Series of Securities. Unless otherwise specified in a Board Resolution, a supplemental indenture hereto or an Officer’s Certificate
delivered pursuant to Section 2.2 of this Indenture with respect to a particular Series of Securities, such conversion shall
be at the spot rate for the purchase of the designated currency as published in The Financial Times in the “Currency Rates”
section (or, if The Financial Times is no longer published, or if such information is no longer available in The Financial Times, such
source as may be selected in good faith by the Company) on any date of determination. The provisions of this paragraph shall apply in
determining the equivalent principal amount in respect of Securities of a Series denominated in currency other than Dollars in connection
with any action taken by Holders of Securities pursuant to the terms of this Indenture.


 


All decisions and determinations
provided for in the preceding paragraph shall, in the absence of manifest error, to the extent permitted by law, be conclusive for all

Section 10.16.        Judgment
Currency.


 


The Company agrees, to the fullest
extent that it may effectively do so under applicable law, that (a) if for the purpose of obtaining judgment in any court it is necessary
to convert the sum due in respect of the principal of or interest or other amount on the Securities of any Series (the “Required
Currency”) into a currency in which a judgment will be rendered (the “Judgment Currency”), the rate of exchange
used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required
Currency with the Judgment Currency on the day on which final unappealable judgment is entered, unless such day is not a New York Banking
Day, then the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase
in The City of New York the Required Currency with the Judgment Currency on the New York Banking Day preceding the day on which final
unappealable judgment is entered and (b) its obligations under this Indenture to make payments in the Required Currency (i) shall
not be discharged or satisfied by any tender, any recovery pursuant to any judgment (whether or not entered in accordance with subsection
(a)), in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the actual receipt,
by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable
as an alternative or additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such
actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable, and (iii) shall not be affected
by judgment being obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York Banking Day”
means any day except a Saturday, Sunday or a legal holiday in The City of New York on which banking institutions are authorized or required
by law, regulation or executive order to close.


 


Section 10.17.        Force

In no event shall the Trustee
be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly
or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism,
civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities,
communications or computer (software and hardware) services, it being understood that the Trustee shall use reasonable best efforts which
are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.


 


Section 10.18.        U.S.A.
Patriot Act.


 


The parties hereto acknowledge
that in accordance with Section 326 of the U.S.A. Patriot Act, the Trustee is required to obtain, verify, and record information
that identifies each person or legal entity that establishes a relationship or opens an account with the Trustee. The parties to this

ARTICLE XI.

SINKING FUNDS


  


Section 11.1.          Applicability
of Article.


 


The provisions of this Article shall
be applicable to any sinking fund for the retirement of the Securities of a Series if so provided by the terms of such Securities
pursuant to Section 2.2, except as otherwise permitted or required by any form of Security of such Series issued pursuant to
this Indenture.


 


The minimum amount of any sinking
fund payment provided for by the terms of the Securities of any Series is herein referred to as a “mandatory sinking fund
payment” and any other amount provided for by the terms of Securities of such Series is herein referred to as an “optional
sinking fund payment.” If provided for by the terms of Securities of any Series, the cash amount of any sinking fund payment
may be subject to reduction as provided in Section 11.2. Each sinking fund payment shall be applied to the redemption of Securities
of any Series as provided for by the terms of the Securities of such Series.


 


Section 11.2.          Satisfaction
of Sinking Fund Payments with Securities.


 


The Company may, in satisfaction
of all or any part of any sinking fund payment with respect to the Securities of any Series to be made pursuant to the terms of such
Securities (1) deliver outstanding Securities of such Series to which such sinking fund payment is applicable (other than any
of such Securities previously called for mandatory sinking fund redemption) and (2) apply as credit Securities of such Series to
which such sinking fund payment is applicable and which have been repurchased by the Company or redeemed either at the election of the
Company pursuant to the terms of such Series of Securities (except pursuant to any mandatory sinking fund) or through the application
of permitted optional sinking fund payments or other optional redemptions pursuant to the terms of such Securities, provided that such
Securities have not been previously so credited. Such Securities shall be received by the Trustee, together with an Officer’s Certificate
with respect thereto, not later than 15 days prior to the date on which the Trustee begins the process of selecting Securities for redemption,
and shall be credited for such purpose by the Trustee at the price specified in such Securities for redemption through operation of the
sinking fund and the amount of such sinking fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities
in lieu of cash payments pursuant to this Section 11.2, the principal amount of Securities of such Series to be redeemed in
order to exhaust the aforesaid cash payment shall be less than $100,000, the Trustee need not call Securities of such Series for
redemption, except upon receipt of a Company Order that such action be taken, and such cash payment shall be held by the Trustee or a
Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying
Agent shall from time to time upon receipt of a Company Order pay over and deliver to the Company any cash payment so being held by the
Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that Series purchased by the Company having
an unpaid principal amount equal to the cash payment required to be released to the Company.


 






    44 


     


    

 


Section 11.3.          Redemption
of Securities for Sinking Fund.


 


Not less than 45 days (unless
otherwise indicated in the Board Resolution, supplemental indenture hereto or Officer’s Certificate in respect of a particular Series of
Securities) prior to each sinking fund payment date for any Series of Securities, the Company will deliver to the Trustee an Officer’s
Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that Series pursuant to the terms of that
Series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied
by delivering and crediting of Securities of that Series pursuant to Section 11.2, and the optional amount, if any, to be added
in cash to the next ensuing mandatory sinking fund payment, and the Company shall thereupon be obligated to pay the amount therein specified.
Not less than 30 days (unless otherwise indicated in the Board Resolution, Officer’s Certificate or supplemental indenture in respect
of a particular Series of Securities) before each such sinking fund payment date the Securities to be redeemed upon such sinking
fund payment date will be selected in the manner specified in Section 3.2 and the Company shall send or cause to be sent a notice
of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in and in accordance with
Section 3.3. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 3.4, 3.5 and 3.6.
